Summary:The welding process is one of the most important application in uncertain sampled-data system. In this paper, the study deals with a fundamental issue of non-fragile control for a class of uncertain sampled-data system. The focus is to design non-fragile controller against possible perturbation by combining pole contraints theory and the linear matrix inequality approach which results in sampled-data system is D-stable, moreover, the existence condition and the design approach of non-fragile controller are derived. Finally, simulation examples are proposed to demonstrate the effectiveness of the attained algorithm.
